Operating Heater

Continued

2.The receiver continuously receives signals from the hand-held remote to control the room temperature. If the hand-held remote is misplaced, obstructed or for any reason cannot transmit to the receiver, the receiver will shut off the fireplace after 8 minutes.

Key Pad Lock Feature

This feature allows the user to lock/unlock the keypad on the hand-held remote in the MANU or AUTO mode to prevent inadvertent operation (i.e. children operating the hand-held remote control, etc.). The keypad is locked in either on or off. Press the POWER and LOCK buttons together to turn the unit on or off.

Inspecting Burners

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

Figure 35 shows a correct pilot flame pattern. Figure 36 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 36

•turn heater off (see To Turn Off Gas to Appli- ance, page 21

•see Troubleshooting, page 25

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.
